( a ) Whether the student had unimpaired vision of wore goggles first was randomly selected . Why is this a good idea in designing the experiment ?
O A. This is a good idea in designing
ing the experiment because reaction times are different
OB . This is a good idea in designing
igning the experiment because the sample size is
is not large enough
OC . This is a good idea in designing the experiment because it controls for any Team
who ARE
arning &quot; that may occur in using the simulator
( 6 ) Use a 95% confidence interval to test if
HIGH
there is a difference in braking time with impaired vision and normal vision where the differences are computed as impaired minus normal
The 85% confidence interval is ( . (Round to the nearest thousandth as needed )
State the appropriate conclusion Choose the correct answer below
